Although I have not used AM recently, partly as a result of my poor voice, I can see the attraction of the mode. It lends itself to home brewing and in the past I have designed and made several AM rigs. At one time they were practically giving away ex PMR AM rigs.
The Fredbox and Sixbox are examples of AM rigs I have designed and made in the past.
Southgate News has announced the formation of an AM Amateur Radio Society.
My thanks to Steve G1KQH for pointing this out.
Many years ago as an experiment I modified my 160m valve Tx to use a form of screen grid modulation that gave a carrier level dependant on the modulation level so it was always 100% modulated, so it looked to others like an SSB signal but no BFO needed to resolve it. When I tried it on air it was met with derision as there was no carrier when I stopped talking. I was told it was probably illegal as no-one had seen it before,so I never used it again.
ReplyDeleteJust recently I saw the same technique described as DSB AM! (in a more modern circuit).
Saves a lot on battery power!
